To all whom it'may concern:

Be it known that we, HARRY L. Bonnnns of a corrugated paper box may be raised and lowered innumerable times without breaking the hinge connection;

A further object is to provide asufiening wire which forms a portion of the hinge for a corrugated paper box, the wire being so secured as to prevent the same from be ing removed from the boX afterbeing in serted.

In the drawings Figure 1 is a fragmental sectional view of our device appliedto a corrugated box with the lid thereof in closed position.

Fig. 2 is a fragmental sectional view taken on the line 22 of Fig. 1, showingthe lid in elevated position.

Fig. 3 is a section taken on the line 33 of Fig. 1.

Fig. 1 is a section taken on the line 4-4: of Fig. 2. y c

Fig. 5 is an enlarged sectional view taken on the line 5-5 of Fig. 2 with the lid thrown entirely back and resting against the body of the box.

In the construction of our device, we provide a body member 5 which is constructed preferably of corrugated paper board, this container being left open on its upper end. Upon the open end of this container is placed a lid constructed of similar material which is provided with depending flanges 7 around three of its sides, the depending flanges fitting outside the vertical walls of the container 5.

In the rear wall of the container is inserted a U-shaped wire 9, said wire extending almost entirely across one of the faces of the container. This wire is provided at its lower end with a hook portion 10, the object of this hook portion being to bind the wire 9 securely within the container body as is illustrated in Fig. a, wherein the hook 10 is shown as cutting into one ofthe walls of the corrugated partition of. which the body of the box or container is construoted. i

Sau'rrounding the portion 11 of the wire 91s a strip of fabric 12, this strip being firmly secured to the upper andlowersurface of the lid (rand along that edge of the lid which is not provided with a depending flange, this wire and fabric forming a hinge.

In order to-prevent the admission ofdust or other foreign substance into the box5, we place a second strip of fabric 13 over a portion of the aforesaid fabric and extending down to the body of the box and being secured thereto; alsoperformingthe function of an additional hinge member, thereby virtuallymaking a double hinge for the lid; t 1

The wire 9 further performs the function of stiffening that portion of the box in which it is inserted and prevents the bulging of the same when the boXis packed, thereby forming a straight hinge. This would be i lnpos'siblewere the strip is only used as a hingeas then the central portion of the body ofthe box could-I bulge outward andthe utility of the hinge be destroyed.

By our invention a hinge is formed which will last as long as the container and without the defectaforementioned. Neither is there any tendency of the hinge becoming loosened when the lid of the box is thrown back as would be the case when a fabric strip only was employed as a hinge, and by the formation of the wire member of the hinge, the hooks 10 gripping into the corrugations prevent the withdrawal of the wire 9.

As perviously pointed out, the strip of fabric 13 has one of its margins secured to the outside of the box and the other margin superimposed and secured over the strip or fabric 12 passing over the wire 9, thus affording two thicknesses of fabric over the wire 9 when the lid is closed. This preventsthe lid along the hinge margin from being pressed downwardly, thus stiffening the lid from upward and downward pres sure along its hinge connection.

It will be further noted that the vertical depending end ofthe wire 9 has a tendency to strengthen and stiffen the corners of the box in which they are located; thus it will be seen that the Wire performs three functions, towit: It acts as a portion of the hinge connection; a stiffening for the edge of the box; and also as a reinforcement for the corners in which they are placed.

In Fig. 5 we have illustrated the con nection of the strip of fabric 13 when the lid is entirely open and thrown back against the rear side of the box, from which it will be observed that-this strip folds upon itself and forms a fold 13 projecting between the top edge of the box and the fabric strip 12.

and wire 11. The effect of this as previously pointed out is to form a dust proof connection between the lid and top edge of thebox 011 the side of the box on which the lid is hinged.

Having fully described our invention, what we claim is:

1. Ahinge for corrugated boxes comprising in combination with a body and lid composed of corrugated material, of a U- shaped wire inserted in the body portion of the box and extending across one side thereof, a strip of fabric surrounding said wire and secured to" the upper and lower faces of, the lid, a second strip of fabric superimposed on that portion of the first mentioned fabric which is secured to the upper surface of the lid extending over said wire and secured to the outside of the body portion of the box. 2. A hinge for corrugated boxes comprising in combination with a body and lid composed of corrugated material, of a U-shaped wire inserted in the body. portion of the box copies of this patent may be obtained for adjacent the corners thereof, hook members formed on each end of the wire for engaging the walls of the corrugations formed in the body portion of the box, a strip of fabric surrounding said wire and secured to the upper and lower faces of the lid a, second strip of fabric superimposed on that portion of the first mentioned fabric which is secured to the upper surface of the lid extending over said wire and secured to the out side of the body portion of the box.

3. A hinge for corrugated boxer-z comprising a U-shaped wire provided with prongs on its terminal portion adapted to be inserted in the corrugations of the body of the box, a strip of fabric material surround ing said wire and having one margin thereof secured to the under side of the box lid and its opposite margin secured to the top surface of the box lid, and a second strip of fabric material superimposed and secured to the first mentioned strip alon one margin thereof and having its opposite margin secured to the exterior surface of the body of the box, said second mentionml strip co-acting with the wire and first mentioned strip in formingthe hinge and as a cover for the opening between the top edge of the box and the box lid.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
